wiring questions..

[floatingwoody2006]

You guys have helped me get my rude running great.. now the final thing before i can get running is the wiring. I plan on adding 2 wallyworld deep cycle batteries for my 24v minn kota. That should be pretty straight forward. But in addition, my bilge, fish finder and lights are 12 volt. All the wiring will be run to a fuse panel already in the boat. If the batteries are wired in series to get 24v, do i need a third for 12v, or if i connect the wires to just the terminals of one battery while in series, would this get me 12v? hopefully i can get er done and get it out the first time this weekend. Thanks!!

Re: wiring questions..

also had a quick charging question.. the auto shutoff on my charger seems to have stopped working. At what voltage shoud i consider my deep cycle's charged?.. Thanks again

Re: wiring questions..

Wire to either of the two batteries wired in series. Are you also using one of the two for a starting battery? If so, I'd install a third strictly for engine starting and feeding the console fuse panel and accessories. Leave the 24V system for the trolling motor only or you risk being left stranded due insufficient battery power to start the motor.

Re: wiring questions..

not using anything but my arm for starting. Batteries are for trolling motor, fish finder, lights, and bilge. So i can wire in series for troller, run say fish finder and lights to one batt, bilge on the other, and still keep it in series? sound like a pretty simple deal. Thanks..

Re: wiring questions..

Um, if I'm not mistaken, wiring the two batteries in series (24 v) will make the entire circuit 24 v. Just conecting the electronics to one battery, but still part of the 24 v circuit, will make it 24 v to your accessories. Check with a volt meter before connecting anything!

Re: wiring questions..

As long as you use the positive and negative of the same battery for each load it will be 12 volt.Try to balance the load as it will be easier to keep the batteries balanced.It is also possible to charge each battery individually.

Whew.. Sticky anyone?

Re: wiring questions..

No -- You cannot split the 12V loads between the two batteries but you can use one of them to power all 12V accessories. No to TTU as well. He will not connect across the 24V leg. Connecting across one battery will still provide 12V. The problem with splitting the 12V loads between the two is that POS on one battery is the same as NEG on the other. So that would create a problem. Just hook all the 12V stuff to one battery and you'll be ok.

Re: wiring questions..

And that's why you cannot split the accessories between batteries. You can however connect all of them to either battery.

Re: wiring questions..

How big of a boat are we talking about? My whole boat is 24v, which of course causes a problem for the VHF, since they are 12v. I like to keep a balance across the batts on the 24v setup so I’m not keen to the idea of pulling 12v from one of the batts for the VHF. I have a small 6a transformer (model 32-12-6) to step down the voltage from 24v to 12v just for the VHF.<br /><br /> http://www.newmarpower.com/dc-dcconvertersstandard/dcdcconvertersstandard.html <br /><br />Otherwise I’m throwing in with UpInSmoke on this, get a 3rd battery for your 12v stuff. Also consider how you are going to be charging all of those batteries. One of the reasons I opted for the transformer, only have/need 24v chargers onboard.
